other than neowin
Neowin is not really a stardock site. We just host it and (IIRC) own a part-share.
The recent posts list as i look at it now, does not do much for my point, ATM, but it is very easy for all 10 links to have nothing to do with GC2. More oftne than not GC2 related topics are overwhelmed here and go unnoticed.
Looking at the full recent posts list, taking the first two pages into account (latest 100 threads) it's currently holding steady at about a 50/50 mix of GC2 and not-GC2. Not quite entirely overwhelmed, but yeah, it's pretty thoroughly mixed. I don't think that causes the GC2 topics to be ignored by those who might be interested in them, though. You'd be surprised how many people do use the direct category pages rather than the recent posts list.
Most of the non-GC2 stuff is from Impulse, which can be relevant to GC2 users who may have issues in need of support in that category. It also sees some non-issue threads discussing games and DRM in general, which are of interest to a fair number of users, even if they're unrelated to GC2 directly (I understand that may not be the case for you guys, but most are not GC2-exclusive gamers). Same goes for the PC categories. The only one that I'd really argue is *completey* irrelevant to GC2 would be the OTF, but there's got to be somewhere for that stuff to go, and at present there's only one OTF thread in the last 100 anyway.
More to the point, I don't think the sharing itself is so much an issue (or at least, as has been said, it's Brad's choice and it won't be changing), so much as the attitudes of the posters. As Starkers said, even if the extra threads (on either side) aren't something of direct interest to any given person, they can serve to expand one's horizons. And if they're not your cup of tea altogether, is it too much to ask to leave them in peace? Yes, this is the internet, but if you're in a public space and some people nearby were discussing something of disinterest to you, or even something you actively dislike, would you jump in and berate them, or just tune them out?
Those reading from the GC2 side may not be aware of it, but yeah, WC has had issues in the past with the community being "unfriendly" at times, to put it simply. Zoomba and ID have both posted on that subject before over there. As the WC forums are much more wide-ranging, things are not moderated the same way as here at GC2, where we actively try to keep things friendly. Maybe that has contributed to letting it get that way; I don't spend much time over there though, so it's not really my place to make that judgement.
At the end of the day though, a bit more respect all around is definitely in order. If people can learn to not jump to assume the worst about someone else's comments (or to just let it slide or alert a moderator if there is no positive interpretation possible), and stop sending things into a downward spiral as often as not, we'll be well on our way to making the whole network a better, more friendly community which everyone will benefit from.
